I am of the cynical viewpoint; they are all at least equally terrible. Some are probably worse than others.

You might have luck if the underlying cause of your PN is known, like B12 deficiency or diabetes, then you change your diet and it gets better. Otherwise they give you drugs like; amitriptyline, lyrica, gabapentin, cymbalta, which don't usually work, although they can be helpful for sleep problems. You might have some luck with them or supplements or who knows...!
